The invention discloses a fuel tank cover plate assembly which comprises a cover plate body and an oil filling pipe. A pressure ring is arranged in the placement cavity; according to the oil tank, a specific dust removal baffling channel and oil condensation baffling channel structure is constructed on the outer side of the oil injection pipe, and when the pressure intensity in the oil tank is higher than the pressure intensity of the external environment, high-pressure gas in the oil tank tends to overflow outwards; overflowed gas firstly enters the oil condensing and baffling channel, and in the channel, due to the special design of the channel structure and the internal surface characteristics of the channel structure, oil components in the gas are condensed under the action of baffling, collision and the like, so that oil collection is realized, and waste and pollution caused by direct overflow of the oil along with the gas are avoided; and the gas subjected to oil condensation treatment is discharged outwards, so that the discharge of oil vapor is effectively reduced.
本发明公开的一种燃油箱盖板总成,包括盖板本体和注油管;所述安置腔中设置有压力环;安置腔的外侧还设置有除尘折流通道和凝油折流通道,本申请通过在注油管的外侧构建了特定的除尘折流通道与凝油折流通道结构,当油箱内部压强高于外界环境压强时,油箱内的高压气体产生向外溢出的趋势,外溢气体首先进入凝油折流通道,在该通道内,由于通道结构的特殊设计以及其内部表面特性,使得气体中的油液成分在折流、碰撞等作用下发生凝聚现象,从而实现油液的收集,避免了油液直接随气体外溢造成的浪费与污染,经过凝油处理后的气体再向外排出,有效减少了油液蒸气的排放。
